besides the fact your pulling #s outa your ass then working backward threw the equation..
for now, ill just ask u the easy ?'s to prove u are insane... ok, ok, u say the human body resistence is close to 0, then why dont u get shocked when u lick both your fingers and put them on both terminals of a 12v batt?
and for your stupid experiment... i hate to tell ya, but the current fora generator isnt deturmined by the size of your shoes(<-wow,lmao)
the rate of induction depends on the magnetic field strenth, how many fields u use around the armature, how fast your spinning the armature, and the amount of size/thicknes/type of stator u use. (and i can tell u that it doesnt take 50000v to jump 5cm, so i doubt very much u were producing 50000v) ... so u end up with a spark jumping from point A to B.. and i hate to burst your bubble again, but if u put your hand between those, the spark will jump back into air to reach point B. (im not shur if u realize or not, so ill tell u, that current take the path of least resistence... so were do u think it will go, threw air, or your stupid fat thick shoes?) now tell me u werent just pulling #s outa ur ass.
